Which balloon has a greater volume an oxygen balloon at 16 grams or a helium balloon at 2 grams?
16 grams of oxygen, O2, is 0.5 mole, 2 grams of helium, He, is also 0.5 mole. They therefore contain the same number of gas "particles" (molecules for O2, atoms for He) and they will have almost identical volumes at the same pressure
How much helium is in a balloon that contains 0.54 grams of gas?
0.54 grams 1 mol = mass / Mr = mass / 4 (Helium's atomic weight is 4, it is a monoatomic gas) 1 mol = 0.54 / 4 = 0.00135 # of molecules of helium in the balloon = 0.00135 * 6.02 * 10^23
If a weather balloon with 2-meter diameter at ambient temperature holds 525 grams of helium What type of electronic probe could be used to determine the pressure inside the balloon?

How much helium is in a balloon that contains 0.54 grams of helium gas?
4 g of Helium will have 6.023 x 1023 atoms and will occupy 22.414 liters. So, 0.54 g of Helium will have 0.37 x 1023 atoms and will occupy 3.03 liters.
How much weight will a helium balloon carry?
You measure the circumference of the balloon which is 46.75 and one cubic foot of hellium and it lifts about 1 ounce of sugar/anything, So one cubic foot of hellium will lift 1 ounce.

How many grams of helium must be added to a balloon containing 8g helium?
Approx 2.7836
How many grams of helium must be added to a balloon containing 8.00 g helium gas to double its volume?

Will nitrous oxide float in a balloon?
No, nitrous oxide has a density of around 1.977 grams/liter, "air" at sea level has a density of 1.2 grams/liter, meaning that nitrous oxide is more dense than air. Helium on the other hand has a density of 0.1785 grams/liter, making it less dense than air... Also making helium a popular choice for filling balloons. Hydrogen is another common balloon filling gas. Although it is highly flammable. (Hindenburg)
How much helium is needed to lift an average human body?
Depends on the weight. Check the MythBusters website, they did an experiment on this.

How many moles are present in 205 g of helium?
Quite a few! 205 grams helium (1 mole He/4.003 grams) 51.2 moles of helium
How many grams are in 5.82 moles of helium?
There are 23.28 grams in 5.82 moles of helium, because 5.82 mol times 4g =23.28 grams
